The Dairy Podcast Show Dr. Glenn Holub: Heat Stress Management in Cows | Ep. 35
As summer approaches, we must be prepared to manage heat stress and prevent losses among our cows. Heat stress can lead to substantial losses in revenue for dairies, so it’s important to turn over every rock in looking for solutions. In this episode, with Dr. Glenn Holub, we explore the impact of heat stress during the early hot days leading up to summer, ways of identifying heat stress signals and physiological changes in cows, effective strategies and systems to minimize heat stress, and common mistakes in managing cow cooling.
“If your cows start telling you that they're hot, but you don't have your cooling system up and running at peak, then it's too late.’’ - Dr. Glenn Holub
